Clicking on the auto-completed search results does not take the user to review-request/user/group. This seems to have been changed in commit 937d9c0 (https://github.com/rajasaur/reviewboard/commit/937d9c098f21e3619691e8d63726b41aea4809aa) to avoid collision with jquery ui's version but seems to have
removed this logic.

Ive added the logic that takes the user to the page when its clicked from the Search box. In addition, Ive also set the default value of "clickToURL" to
false so that other autocompletes like the ones in review page (for user/group) dont automatically take the user to that page when clicked.

What still doesnt work:
1. Just clicking on "enter" key on auto-completed results doesnt take the user to the result page. It only fills in the Search box. But I suppose thats another issue (bug 2779).

1. Tested in Search page by entering review-request/users and made sure it goes to the correct page
2. Verified in the Review request page that selecting a user/group does not open a new page but instead places the users in the required textfield.
